Answer 1

First, I'll mention that there's nothing wrong with the adjectives you've started out with: Difficult, unfriendly, argumentative, uncooperative, etc.

One word that comes to mind, though it's a little dated, is:

contrary

1. opposite in nature, direction, or meaning.

2. perversely inclined to disagree or to do the opposite of what is expected or desired.

In more modern parlance, one thing that comes to mind is that the person might be described as being "hard work" (as well as a variety of slang terms and curse words).

I also think there is a sense in which it is somewhat unlikely that people would use a direct adjective to describe this kind of behaviour, as people generally don't want to be accused of being judgmental, or, in this case, of being exactly what they are accusing the other person of being!

I feel you'd more likely hear gossipy descriptions of the behaviour instead:

He always seems to disagree with everything anyone says!

I agree, he can be very difficult to work with at times.

Yeah, he's definitely hard work!
